I'm new to SDN and I'm trying the opendaylight controller.
I have set it up with running web API and I can't add flows but it recognizes my topology.
I use mininet to create the topology.
Opendaylight helium 2.0.
Does anybody know why i can't select nodes to create my flow?
Here are some images:
Opendaylight can't select node to create flow
I have the same issue, there seem to be more people with the same problem. Here you can find an answer:

They say that it's better to use the REST Interface.

I am trying integrate Camunda spring boot app with Opsgenie space of our project. After adding Java SDK as the dependency, it's possible now to create alert to the Opsgenie project. But i need create incident (it is the type of alert as docs say), but i found only incident Rest API for this purpose - Java API creates only alerts.
Should i write custom implementation of this API method in Java?
Help, please, thank you.
From doc: incidents can be created manually, or their creation can be automated
by consolidating Alerts through the use of Incident Rules
Thats why, maybe, Java API creates only alerts
Yes, you can create incidents. You can use opsgenie-oas project and generate the API client code using open API generator.
Does anyone tell me the proper integration of opendaylight with GNS3
Actually, I want to enable NETCONF in switch for that I use GNS3 but unable to find any proper document for GNS3 integration with opendaylight.
I will recommend that you check the videos by David Bombal on youtube or on Udemy. They provide great resource to integrate Opendaylight with GNS3.
Although I don't know what your project is all about, why not try using RYU controller instead?
I find RYU controller easire to use because of its use of python.
I have already made a Ingestion job using spring batch which reads xml file and ingest into AEM and its working fine.
Now, I am trying to convert this apps into Spring cloud Task. I want to split this apps into 4 different part which is individual apps. I need to connect them into spring cloud data workflow and pass some data and flags based on that next flow will be execute.
Is it possible on spring cloud Task? if yes then how can I bind them? please provide some programming tutorial.
In the recent 1.2.0.RELEASE, we have released a new feature called the "Composed Tasks". With this, you could define a directed graph that's made of several spring-cloud-task (SCT) applications.
Each step in your flow can be an independent SCT application, which you can develop, test, and CI/CD in isolation. Once you're ready to orchestrate them as a composed graph, you'd then register and use them in the specially designed composed-task DSL or the drag & drop GUI.
Checkout this screencast for more details.
I am currently working on software defined networking project. I wanted to know how can we add flows using opendaylight controller.
I tried adding flows using opendaylight controller with postman but they are failing due to 405 method not supported Error message.
There are restAPI available to do this task. Go through opendaylight documentation to find restAPI matching your need.
Maybe this link would help.
Spring XD on YARN: ver 1.2.1 direct binding support for kafka source.
1.I know this is not supported yet(as of ver 1.3.0), any definite date/ver would help our project schedule ?
2.This direct binding for kafka source support is very critical for our project. We are in a situation to totally abandon Spring XD YARN in our project just because of this.
Trying to do
stream create --name directkafkatohdfs --definition "kafka | hdfs"
stream deploy directkafkatohdfs --properties "module.*.count=0"
Hitting the exception "must be a positive number. 0-count kafka sources are not currently supported"
I just want to eliminate the use of message bus/transport(redis/kafka/rabbitMQ) and want to have a direct binding of source(kafka) and sink(sink) in the same YARN container.
1.I know this is not supported yet(as of ver 1.3.0), any definite date/ver would help our project schedule.

Thanks for the interest in Spring XD :).
For Spring XD 1.x, we suggest using composition instead of direct binding with the Kafka bus - or, in your case, the Kafka source. However, apart from that, in Spring XD 1.x it is not possible to create an entire stream without at least one hop over the bus (regardless of the type of bus or modules being used).
We are addressing direct binding (including support for entire directly bound streams) as part of Spring Cloud Data Flow (http://cloud.spring.io/spring-cloud-dataflow/) - which is the next evolution of Spring XD. We are intending to support it as a specific configuration option, rather than as a side-effect of zero-count modules. From an end-user perspective, SCDF supports the same DSL as Spring XD (with minor variations) and has the same administration UI, and definitely supports YARN, so it should be a fairly seamless transition. I would suggest starting to take a look at that. The upcoming 1.0.0.M2 release of Spring Cloud Data Flow will not support direct binding via DSL yet, but the intent is to support it in the final release which is currently planned for Q1 2016.
